Petrol Smell in AC Air

[Xulfiqar]

:*

I had the same masla wid my car..eik din achanak smell ana shuru hogai ..!!
den i checked my fuel tank!!
tu pata chala kisi H*%$$ AHO!
ney uska cover hie utar liya wa tha!!

That is why when I fill up fuel - I get out of the car and open and seal the cap myself. that way they wont scratch my cars paint or worse forget the cap and see me off with a bye bye - buying a german fuel cap for diesel is a pain

It once happened with me when the fuel pump/injector had leaked.
So it could be from the petrol line going into the injectors or injector itself.
Ur smelling it from the ac blower because when the car engine is on, the fuel pump only works then otherwise not.So its from the pump or after it because before the pump, the petrol would leak all the time.

check the return pipe of petrol for leaks from the fuel pump... i think the problem is with it
as you are on CNG the petrol is not going in the carb so the return pipe may be leaking and causing that smell and when u switch to petrol.. the the petrol usage starts to the ratio of return is slow so the leaks gets off
